It’s always good to remember that weather is both heartless and beautiful, to watch out for its vagaries and to enjoy its beauty. The Weather Network Gallery is a good place to browse through hundreds of beautiful images in several categories: scenes of the season, active weather, beautiful weather, animals, gardening, outdoor activities, and travel.

City of Toronto
5:23 PM EST Saturday 04 January 2014Special weather statement
for City of Toronto continued

Winter storm with heavy snow later Sunday and Sunday night, with mixed precipitation for some regions. Windy and sharply colder again Monday with some blowing snow and lake effect snow-squalls.

Old man winter is about to have another go at Southern Ontario as a winter storm developing over Oklahoma threatens the region.

A weak cold front from a separate weather system affecting Northern Ontario will slip into Southern Ontario tonight. This front will give a few centimetres of snow to many areas by Sunday morning, with 5 cm or more falling in locales east of Lake Huron to the south of Georgian Bay. This front will likely stall north of lakes Erie and Ontario on Sunday.

Meanwhile, a low pressure system developing over Oklahoma today will intensify and track northeastward along the line of the stalled front, crossing Southern Ontario Sunday night.

Some disorganized snow is expected on Sunday over some regions. As the deepening low approaches, the snow will become heavy over Southwestern Ontario Sunday afternoon and over the remaining regions Sunday evening. The snow will likely change to some rain near Eastern Lake Erie and Lake Ontario as well as parts of Eastern Ontario later Sunday evening. There is also a threat of some freezing rain in these areas. Any freezing rain that occurs will have virtually no impact on hydro for those areas impacted by the recent ice storm. But more significant freezing rain may impact travel to some degree over Eastern Ontario. Freezing rain warnings will likely be issued later tonight. The precipitation will taper off overnight Sunday or by early Monday in the east.

It appears that regions north of a line from roughly Leamington to London to Barrie to Pembroke will receive snowfall amounts of 15 to 20 cm. Amounts will likely be up to 5 cm south of that line with locally 10 cm in some areas.

In the wake of the storm, bitterly cold west to northwest winds will return on Monday, producing blowing and drifting snow in areas which receive the most snow from the storm. Furthermore, intense snow squalls are forecast to develop off Lake Huron and Georgian Bay Monday and persist into mid week.

Travel conditions are expected to deteriorate and become hazardous due to accumulating snow and poor visibility in heavy snow over Southern Ontario Sunday. If freezing rain falls, untreated surfaces may quickly become icy and slippery.

There is still some uncertainty as to the exact track of the storm centre and where the freezing rain and heaviest snow will fall. Environment Canada will continue to monitor this evolving situation and issue warnings accordingly.

It should be noted that widespread dangerous wind chills are likely especially from Monday night through Wednesday as some of the coldest air in years seems poised to settle across the region accompanied by brisk winds.

The public is advised to monitor future forecasts and warnings as warnings may be required or extended. Please monitor the latest forecasts and warnings from Environment Canada at http://www.weatheroffice.gc.ca.

The map above shows anomalies compared to the average from 1981-2010, which in itself is a shifted baseline since temperatures started to warm up noticeably in 1986.

Over 16,000 high-temperature records were broken in the U.S. during March 2012, and by large margins of around 4.5° Centigrade or 9.8° Fahrenheit. The U.S. Northeast was particularly warm, which enabled tornadoes to form. The Pacific Northwest coast was cooler than usual right along the ocean. All regions except the Pacific Northwest had unusual temperatures, with either above-average temperatures or an unusual number of warm days: “NOAA confirms unprecedented warmth in March.” Maps are available at NOAA.

The map below shows state temperature records for March. The red is warmest in 118 years. The orange is warmest in 113 – 117 years, and so on.

What really happened to the Edmund Fitzgerald? Some new evidence from Dive Detectives suggests that it was broken up by extra-high rogue waves during a hurricane-force storm. The investigating board was quick to blame employee error in leaving hatch covers improperly latched–although the sailor’s lives depended on doing it right. However, other ships on the Great Lakes are known to have broken in half without warning. If it weren’t for the testimony of a single survivor, it, too might have been written off as employee error. Another ship manufactured in the same way developed cracks and broke up while being towed away for demolition. At the time the Edmund Fitzgerald sank, the load limits had been increased so that it was carrying more than it was designed for and riding lower in the water. It had been inspected for structural safety only ten days before.

The Edmund Fitzgerald

Both ships are lakers, long, broad ships limited by the size of the smallest locks that they’ll pass through. The assumption in building them is that the lakes do not develop waves large enough to, say, lift the ends of the ship and leave the middle unsupported or vice versa, or to twist it like a sponge. Ocean-going ships, or salties, are shorter, with the bridge in the middle to help reinforce the ship’s body. The superstructures of lakers are at the ends, leaving a large area free for cargo loading–but leaving the middle weaker.

Scientists and weather forecasters are worried about the fate of the capital city, Bangkok. It’s built on a delta of the river Chao Phraya, and has canals as well as roads (flood map).

* Weather patterns are changing and rainfall patterns are becoming more erratic.Typhoons may appear in unexpected places.

* Typhoons have increased from one every 7 or 8 years to one every 3 or 4 years

* The temperature in Thailand has risen two degrees in the last forty years. Consequently, storms have more energy and are more intense.

* Precipitation during the monsoon has risen by 15%. During the rainy season, a metre of rain can fall in less than an hour.

In addition, the city will end up under water:

* The sea level is rising 3 mm per year.

*The city is based on a river delta. Bangkok is sinking into its soft clay substrate about 4 cm a year as water is pumped out.

* In a really big storm, as much as 30 square km will be flooded with overflow from the river and polluted water from the canals.

Bangkok's flood embankments

The King, a hydrological engineer, has made flood control a priority for thirty years. The city is protected from flooding by overflow ponds and channels that take water from upriver directly to the sea. Pumps can lower the level of the canals 20 cm, helping the city to drain. But it’s not enough to control the damage from typhoons and rising sea levels. But there’s no magic in mega0projects. People are leaving their homes near the canals. They remember the great flood of 2538 (1995 in our calendar). They’re piling up sandbags and building barriers and raising their houses.

Coastal erosion is fierce and soil is constantly being washed away in the southern part of the city. One temple has been surrounded by water in the last twenty years and the lower levels are flooded. The village it served has been washed away in the last fifteen years. Only the telephone poles remain.

New York City is another city that is vulnerable to rising sea levels.
